Hello,
This series adds support for Inline ECC in DDR for AM64X, AM62X, AM62AX, AM62PX, J721E, J721S2, J722S and J784S4 devices.
(1/9) Add ss_cfg reg entry (2/9) Enable ECC priming with BIST engine (3/9) Add a function to store base address and size of RAM's banks in a 64-bit device private data (4/9) Setup the ECC region start and range (5/9) Enable ECC 1-bit error, 2-bit error and multiple-bit error interrupts (6/9) Add CONFIG_K3_INLINE_ECC (7/9) Remove 'ti,ecc-enable' flag (8/9) Set default NR_DRAM_BANKS to 2 (9/9) Pull Redundant DDR functions to a common location and Fixup DDR size when ECC is enabled

Changes since v5:
Add support for J722S EVM
v5: https://lore.kernel.org/u-boot/20241213103129.332246-1-s-k6@ti.com/
Changes since v4: 1. Make dram_init and dram_init_banksize weak at mach-k3/ and define at board/ti/ 2. Remove 'ti,ecc-enable' flag 3. Minor changes like patch order change (8/8 in v4 to 1/9 in v5), use 'u64'
v4: https://lore.kernel.org/u-boot/20241021044024.835846-1-s-k6@ti.com/
Changes since v3: Pull redundant DDR functions to arch/arm/mach-k3/*
v3: https://lore.kernel.org/all/20240523050430.455201-1-s-k6@ti.com/
Changes since v2: Removed 'default n' in Kconfig as that is default setting
v2: https://lore.kernel.org/u-boot/20240510084707.1903133-1-s-k6@ti.com/
Changes since v1: Add support for J7* devices.
v1: https://lore.kernel.org/u-boot/20240131060213.1128024-1-s-k6@ti.com/
